I'm not sure cuz like I said I don't use a scanner, you'll find most people don't. The reason is Linux is close to bulletproof when it comes to viruses for a few reasons, most viruses written are for MS systems (as we've seen the last couple months . Other reason is since almost all the software is open source and alot of people do there own compiling that stuff would be noticed and the word would be sent over the hills like wildfire. (not a bad way of putting it for someone who lives in the city eh)? Also nobody but root would even have the permissions to get at the vital files to infect them. Also since config files are in text form IF something was changed you'd see it. and the list goes on.

the only virus scanner I know of which runs on linux systems is just a cobble of FIle::Scan and is for checking microsoft docs or mail folder contents stored on linux file/mail servers. We do this to protect the windows community. If you're running *nix, then it's pretty much a non-issue.
